Help!

Sarah • 💑 💍 to my best friend, We have a beautiful 3 yr old boy 3/21/16 👦 and, a baby girl 👧 born 1/29/19 and just found out I’m pregnant with #3 due September 2020 This will be our last one 👶 🍼

I’m bad at reading these, but did I ovulate on the 1st of January? Or te day before. I can tell you that my LH was at peak on the 30th & 31st. Thanks!
